BATT Score (Trauma Hemorrhage / TXA)
BATT score (Ageron 2019): age, systolic BP, and GCS bands plus respiratory, heart-rate, penetrating-injury, and high-energy items give a 0–27 prehospital trauma score; ≥ 2 has guided tranexamic-acid use.

Example
- Age
- 70 years
- Systolic BP
- 80 mmHg
- GCS
- 14
- Abnormal respiratory rate or SpO₂
- No
- Heart rate high
- Yes
- Penetrating injury
- No
- High-energy mechanism
- No
Result: BATT score 7 — at or above the TXA-consideration threshold (>= 2).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- < 2
- Below the threshold.
- >= 2
- At or above the tranexamic-acid-consideration threshold. Age/SBP/GCS bands plus RR/SpO2, HR, penetrating, high-energy. A risk score, not a TXA order.
What you enter
- Age
- Systolic BP
- GCS (3–15)
- Abnormal respiratory rate or SpO₂
- Heart rate high
- Penetrating injury
- High-energy mechanism
